In
mathematics, an
image is a value or set of values of a
function.
Specifically, let
f be a function from the
set X to the set
Y.
If
a is an element of
X, then its image under
f is the value
f(
a).
If
A is a
subset of
X, then its image under
f is defined to be
f(
A) := {
f(
a) :
a in
A}.
Finally, the image of
f itself is
f(
X), the same as the
range of
f.
In
religion, an
image is an
idol or
icon.
In
philosophy, an
image is a
conception or
idea.
In
Comics,
Image is a publisher of such characters as Spawn. See
